provements in motion, controlling mechanisms, and is .a division .of,my application filed. May 5th, 1919-, S erial' No. 294,891.

The object of my invention is to maintain an even andsteady aressure on the motion controlling m'echanismto allow a steady predeterminedmovement thereof under. normal on it n andpr rent h ra m veme tliereof under, abnormal conditions.

Another object of my invention is to provide afdevice of theabovecharacter which is ripheral grooves 7, the walls of which coni simple and durable, and having certain details of structure and combinationof parts hereinafter more fully described.

In the accompanying drawin'gs Figure 1 is a side elevation of myimproved motion controllingmechanism, show ing the employment. of a; spring;

Figure 2 is a top plan view of Figure 1;

Figure 3 is a verticaltransverse sectional view taken on the line 33 of Figure 1;

Figure 4 is a side elevation of the cam carrying lever partly broken away, showing a weight employed instead of the spring;

Figure 5 is a top plan View of Figure 4, partly broken away.

Referring now to the drawings, 1 represents a member, the motion or movement of which in either direction is to be controlled and which is connected to the lever 2 at 3. This is shown as a pivotal connection, but it may be rigid in the application of this mechanism to certain devices or machines. The lever 2 is pivotally connected at 4 to the base or frame 5 which may be of any desired character, and, as shown in Figure 1, is partly broken away to more fully show the operating mechanism.

r The lever 2, intermediate its ends, has rotatably mounted thereon thecam 6 whichhas its outer face provided with a series of peverge or taper, as fully shown in Figure 3 of the drawings. I

The base or frame 5 is provided with a shaft 8, which carries a pulley 9 at one end and over which passes the continuously driven belt 10, so that the shaft 8 is continuously rotated. The opposite endof the shaft is provided with a wheel 11 and its outer face has a series of peripheral ridges which are wedge-shape in cross section to correspond with the grooves 7 in the periphery of the cam 6, and are adapted to extend into the same, as shown inv Figure 3 of the drawings. Connected to the outerfree end of the lever, 2 s a spring 12wlnch draws the lever 2 down, .so ithat the cam 6 frictionally enthe same being continuouslyrotated, and the cam is slowly rotated to allow the gradual downward movement of the lever 2 under the tension of the spring or weight. Should this member 1 cease to move for any reason, the spring would not draw the lever down, but there would be a slipping action between the wheel 11 and the cam 6 until the member 1 had again started to move, when the movement of the lever 2 would be controlled by the cam.

Having. thus described my invention, what I claim as new and desire to secure by 7 Letters Patent, is

1. A motion controlling mechanism comprising a movable member, yielding means for imparting movement to said member, and a friction driven controlling device for positively regulating the advance movements of said movable member.

2. A motion controlling mechanism comprising a movable member, yielding means connected to said member, and a friction driven controlling device for positively regulating the advance of said movable member.

3. A motion controlling mechanism comprising a movable member, a pivoted yielding'lever connected'to said member, and a friction driven controlling device for posi tively regulating the advance of said lever for'regulating the movement of said movable member. e

4.. A motion controlling mechanism comprising a movable member, a pivoted yieldmg lever connected to said member, and a friction driven cam carried by the lever for positively regulating the advance of said lever for regulating the movement of said movable member.

5. A motion controlling mechanism comprising a movable member, a pivoted yielding lever connected to said member, a cam rotatably carried by the lever, and a continuously driven wheel engaging the cam for driving the same and positively regulating the advance of said lever for regu lating the movement of said movable member.

6. A motion controlling mechanism comprising a movable member, a pivoted yielding lever connected to said member, a cam rotatably carried by the lever and having peripheral grooves in its periphery, and a continuously driven Wheel having peripheral projections entering the grooves in the cam for driving the same and positively regulating the advance of said lever for regulating the movement of said member.

7. A motion controlling mechanism comprising a movable member, a pivoted yielding lever connected to said member, a cam rotatably carried bythe lever and having peripheral tapering grooves in its periphery, and a continuously driven Wheel having peripheral tapering projections entering the grooves in the cam for driving the same and positively regulating the advance of said lever for regulating the movement of said member.

8. A motion controlling mechanism comarising a movable member a )lVOtGCl ielding lever connected to said member, a cam carried by the lever, and a continuously driven Wheel engaging the cam for driving the same and positively regulating the advance of said lever for regulating the movement of said member and to allow a slipping between the Wheel and cam when the movable member is not in motion.

9. A motion controlling mechanism comprising a movable member, a lever pivoted at one end and its opposite end connected to the movable member, yielding means for said lever, a cam rotatably carried by the lever intermediate its ends and having peripheral tapering grooves in its periphery, and a continuously driven wheel with tapering peripheral projections entering the grooves in the cam for driving the same and positively regulating the advance of said lever for regulating the movement of the lever.

In testimony whereof, I afiix my signature.
